It doesn't work, but neither does this:

  stap -e 'probe begin { log ( "hello " @1 ) }' world

So this isn't really an issue with the preprocessor.  I think the way 11208 was
implemented prevents the @1 token replacement from being noticed when looking
ahead to merge strings.  In fact, even the ("/usr" @1 "/bin") example given in
NEWS doesn't parse for the same reason.  I'll open a separate bugzilla on this.
